The thought of not having anything significant to remember a week by, and then thinking about how finite those are seems to depress me more than inspire.
I feel the same way, and also about those apps people use to record a short clip or take a photograph every day. But I gather they are relatively popular, so what do I know!
I've been using one of those "short clip everyday" apps for the last 6 years. The only noticeable effect it's had on my life is that I have mundane/everyday/real-life footage of people/pets who have passed away unexpectedly. So when family members are looking for a way to remember them, they tend to ask me if I can dig up any of my "one seconds." It's a bittersweet job, but I'm glad I'm able to provide some comfort that way.
